QX3 Digital Image Gallery

Felt Tip Marker

Felt tip markers are rapidly becoming a favorite industrial marker because of their extreme versatility. New models are capable of being either permanent, erasable with a dry cloth or eraser, and erasable with common solvents. In order to more closely examine a permanent marker, we stuck one on the QX3 stage and took some digital images.

These images were captured using the oblique illuminator built into the microscope head with the assistance of a Dolan-Jenner Model 180 fiber optics illuminator using a 150 watt projection lamp. The light pipes of the illuminator were placed at approximately a 45-degree angle with respect to the optical axis of the microscope and were positioned to evenly illuminate the specimen. A 2-inch square section of black paper was placed over the diffusion filter on the stage of the microscope to avoid any glare from transmitted illumination.
